New study puts D.C.-area highways among nation's most unreliable

A study by the Texas Transportation Institute says stretches of Interstates 70 and 95 as well as parts of the Beltway are among the country’s most unreliable highways.

The study specifically breaks down the worst of the worst roads commuters travel daily.

The Texas Transportation Institute and traffic tracking company Inrix compiled the rankings of the most unreliable roadways, in other words, corridors that delay us the most.

Five of the nation's 45 worst highways are in the D.C area, including I-70 between Route 144 and Route 15 in Frederick, I-95 southbound between I-395 and Russell Road, and the inner loop of the Beltway between Springfield and New Hampshire Avenue.

New projects like the inter-county connector, HOT lanes on the Beltway and Metro expansion are expected to ease some of the congestion. It can hardly get any worse, commuters say, especially at the outer loop of the Beltway between Route 1 and Georgia Avenue in Maryland, which was named the third slowest stretch of road in the country during rush hour.

Here's where D.C. area roads rank among the most unreliable roads calculated by the study:
